Squeak is the girlfriend of Bernard, a soldier in the Barksdale organization. Bernard was responsible for supplying the organization with disposable mobile phones and was told to buy no more than two phones at any one outlet and provide receipts for his purchases. Squeak's nagging convinced Bernard to start breaking these rules.
Squeak was an old associate of Bubbles and their association allowed the police to use her as an inroad to the Barksdale organization. Bubbles put Squeak and Bernard in touch with Lester Freamon who was a posing as a conman who could provide them with the phones at lower price. With Squeak's encouragement, Bernard accepted Freamon's offer and began buying solely from him on the condition that he provide him with receipts. Freamon gave Bernard pre-wiretapped phones that eventually brought down the Barksdale organization. When the investigation was closed with the arrest of Avon Barksdale Bernard and Squeak were also brought in. Bernard joked that he could not wait to go to jail to get away from Squeak.
